MITSUBISHI PLC protection and chain procedures.
Protection and chain is an indispensable part of the program, must be carefully considered.
It can avoid the control logic confusion caused by illegal operations AJ55TB3-8D datasheet PDF catalog AJ55TB3-8D PDF datasheet AJ55TB3-8D
MITSUBISHI PLC initialization procedure. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc AJ55TB3-8D datasheet PDF catalog AJ55TB3-8D PDF datasheet. .
MITSUBISHI PLC program simulation debugging
The basic idea of program simulation debugging is,
In order to facilitate the form of simulation to generate the actual state of the scene,
Create the necessary environmental conditions for the operation of the program.
Depending on the way the field signals are generated,
The simulation debugging has two forms of hardware simulation and software simulation AJ55TB3-8D datasheet PDF catalog AJ55TB3-8D PDF datasheet. Enter 32 points.
5mA DC24V.
Response time: 0.3ms.
32 point 1 public.
Output 32 points.
DC12/24V.
Leakage current: 0.1mA OFF.
Response time: 1ms. 32 point 1 public.
Protection function.
Surge.
40 pin connector.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the historry of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order AJ55TB3-8D datasheet PDF catalog AJ55TB3-8D PDF datasheet.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic AJ55TB3-8D datasheet PDF catalog AJ55TB3-8D PDF datasheet.
And the control principle is decentralized, centralized and hybrid control three.
